  • Device for facilitating the doffing of full bobbins on fly-frames
    Patent number: 4137701
    Abstract: The doffing of full bobbins built on spools placed on the vertical spindles of fly-frames equipped with revolving flyers is performed by combining gripping means such as resilient clips carried by each flyer with retaining means such as an annular groove formed at the upper end of each spool. The releasable axial coupling thus provided is capable of temporarily supporting a spool and full bobbin in the top position while the spindle is moved downwards in order to remove the spool.
